US Patent 7297000 Periodic table of the elements in three dimensional form

Disclosed is a three dimensional arrangement for the Periodic Table of the Elements that is based on an elliptical rather than rectangular arrangement represented in conventional charts. The three dimensional arrangement contains a continuous unidirectional periodic spiral of objects, the spiral having a substantially elliptical shape, and each object representing a different chemical element; the objects positioned so that chemical elements in a period are in a single spiral loop, and each successive period has a larger circumference than a preceding period; and the objects positioned so that chemical elements in a chemical group are in substantially the same vertical plane.
